The F10 Fresnel is made to match the size of traditional 10 inch Fresnel lights such as a 5K or 2500W tungsten HMI, with a 250mm diameter lens made from real glass. The size of this Fresnel allows filmmakers to get an impactful hard light while maintaining a soft, subtle quality that is perfect for dramatic expression. The Fresnel is also compatible with Aputure's F10 Barndoors, which provides large, adjustable blades that have been made to properly cut off the light from the large Fresnel. When combined with the Aputure LS 600d, the device can generate more than 200,000 lux at 1 meter.
